INTRODUCTORY. 


Wk  have  endeavored  in  this  Catalogue  to  place  before  those  interested  in  School  Construction 
and  Architecture  a complete  work,  covering-  the  whole  system  of  Heating,  Ventilating  and  Plumbing. 

Our  Sanitary  Appliances  in  the  way  of  Plumbing  hardly  need  any  comment,  our  name  being 
synonymous  with  the  very  best  work  and  the  latest  improvements  in  that  line.  The  fixtures,  spe- 
cially designed  for  use  in  Schools,  are  the  outcome  of  many  y'ears  of  experience  and  careful  con- 
sideration, and  they  have  also  been  fully  tested  by  actual  use  in  many  of  the  best  Schools  and 
found  in  every'  case  to  be  most  satisfactory'. 

In  the  department  of  Heating  and  Ventilating,  our  engineers  are  men  of  long  and  extensive 
experience,  and  are  therefore  enabled  to  adapt  a system  to  the  requirements  of  any  building,  no 
matter  what  the  conditions  may  be.  The  examples  presented  in  this  book  are  only  a few  ol  those 
in  which  our  Heating  Apparatus  is  placed.  We  do  not  claim  that  these  arrangements  are  the  best 
for  all  buildings,  but  they  are  the  best  possible  systems  for  the  Schools  they  are  placed  in,  consid- 
ering the  plans,  location  and  conditions  of  the  buildings. 

We  design  and  construct  Heating  Apparatus  to  work  by  the  gravity  supply'  and  exhaust  fan 
system  ; also  by'  the  plenum  or  pressure  system.  We  design  the  Apparatus  to  work  by  warm  air 
furnaces,  Hot  Water  or  by  Steam  heat,  as  may  best  suit  the  requirements  of  each  case. 

Communicate  with  us  before  adopting  any  plans  for  your  building. 

Yours  very'  truly',

WHICH  IS  THE  BEST  SYSTEM  ? 


Shall  it  be  warm  air,  by  the  aid  of  furnaces  ? Shall  it  be  by  hot  water  ? Or  shall  it  be  by  steam  ? 
No  engineer  can  say  that  any  system  is  best  under  all  conditions,  for  what  would  be  an  entirely  satisfac- 
tory apparatus  in  one  building  may  be  utterly  inadequate  in  another,  because  the  peculiar  surroundings 
may  make  hot  water  preferable  to  steam  or  warm  air. 

The  location  of  the  building,  the  mode  of  its  construction,  the  exposure  it  presents  to  the  prevail- 
ing winds,  the  size  and  the  number  of  its  windows,  and  the  manner  in  which  the  room  partitions  are  con- 
structed, are  all  conditions  that  materially  affect  the  working  of  a heating  and  ventilating  apparatus,  and 
which  have  to  be  carefully  studied  by  the  heating  and  ventilating  engineer. 

Any  School  Board  or  Committee,  in  taking  up  this  question,  should  communicate  with  us  and 
secure  our  co-operation  with  the  architect  whom  they  have  appointed  to  make  the  plans  of  the  proposed 
structure.  Our  engineer  can  then  go  into  the  matter  and  co-operate  with  the  architect  for  the  determi- 
nation of  the  best  system  required  to  meet  all  the  conditions  that  present  themselves. 

We  do  not  make  any  charge  for  this  service,  provided  that  our  apparatus  is  adopted.  We  do  not 
desire  to  construct  the  plant,  but  prefer  that  the  work  of  construction  be  done  by  a local  contractor. 
The  School  Board  will  then  have  the  advantage  of  securing  the  best  system  for  the  building,  and  at 
the  same  time  take  advantage  of  local  competition  when  getting  bids  for  the  work.  Our  boilers, 
radiators  and  materials,  which  go  into  the  construction  of  the  apparatus,  cost  no  more  than  those  of  any 
other  make  of  equal  merit,  and  they  can  be  obtained  by  any  local  contractor  who  may  be  successful  in 
securing  the  contract.  We  supply  working  plans  for  the  system,  and  when  requested  we  can  make 
arrangements  by  which  the  work  may  be  inspected  by  our  representative  when  completed,  to  see  that  it 
is  done  in  accordance  with  the  requirements  of  the  specifications. 

WHEN  SHOULD  THE  HEATING  APPARATUS  BE  DECIDED  UPON  ? 

1 his  should  be  clone  as  soon  as  the  general  outline  of  the  building-  has  been  determined  on,  before 

o o 

any  working  plans  have  been  made.  In  other  words,  the  heating  and  ventilating  should  be  treated  as 
one  of  the  primary  requisites  of  the  structure. 

IMPORTANCE  OF  THE  SUBJECT  OF  VENTILATION. 

\\  e must  have  fresh  air  in  abundance  for  our  children,  if  the)-  are  to  become  strong  and  healthy 
men  and  women.  I his  fact  has  long  been  recognized  by  those  who  have  thought  much  on  the  subject, 
and  those  who  have.-  not  thought  about  it  may  have  been  in  rooms  where  the  air  was  so  stifling,  for  the 
want  of  ventilation,  that  the)-  were  glad  to  leave  them  as  quickly  as  possible  ; and  yet  these  very  people

will  allow  their  children  to  attend  school  and  live  in  ]iist  such  an  atmosphere  for  hours  at  a time,  and 
then  wonder  why  they  have  become  so  subject  to  diseases  and  why  the)'  take  cold  so  easily. 

The  cause  of  fretfulness,  lack  of  application,  and  other  mental  and  bodily  diseases  of  the 
scholars,  in  nine  cases  out  of  ten,  can  be  traced  directly  to  the  school  room,  because  of  its  bad  ventila- 
tion and  the  absence  of  the  proper  supply  of  fresh  air,  anti  also  at  times  to  the  defective  system  of 
i so  called > sanitary  closets.  Why  should  we  allow  such  conditions  to  exist?  Why  do  we  neglect  to 
supply  the  necessary  fresh  air  and  proper  ventilation  when  it  can  be  so  easily  obtained  ? Is  it  not 
because  we  are  careless,  and  do  not  bestow  the  time  and  attention  necessary  for  the  consideration  of 
these  most  important  subjects  ? A very  large  proportion  of  our  Schools  have  no  means  provided  for 
getting  fresh  air  other  than  by  opening  the  doors  or  windows,  a very  expensive  as  well  as  dangerous  way 
of  obtaining  it  ; expensive,  because  more  heat  will  be  lost  in  one  hour,  if  the  windows  are  left  open  one 
foot  at  the  top,  than  would  be  necessary  to  keep  the  room  warm  for  the  whole  da)’ ; dangerous,  because 
of  the  injurious  drafts  and  the  colds  and  other  ailments  to  which  the  scholars  are  being  exposed. 
Apart  from  its  being  both  expensive  and  dangerous,  it  is  a very  unsatisfactory  way  of  obtaining  fresh 
air  and  ventilation,  for  as  there  is  no  way  of  producing  a circulation  except  by  the  pressure  of  the 
cold  air  from  the  outside,  it  follows  that  the  temperature  of  the  room  in  the  vicinity  of  the  window  will  be 
cold,  while  the  space  on  the  opposite  side  or  end  will  be  too  warm  and  only  partially  ventilated,  if  at  all. 

For  these  reasons  no  rooms  where  a number  of  people  congregate  should  be  used,  that  are 
not  provided  with  a proper  inlet  that  will  supply  fresh  air  without  danger  of  draft,  and  further 
supplied  with  a proper  system  of  ventilation. 


NATURAL  LAWS. 


Nature  has  provided  certain  elements  which  we  may  utilize  in  the  production  and  diffusion  of 
heat,  and  the  circulation  of  fresh  air  and  the  removal  of  foul  air  from  buildings.  The  degree  of 
intelligence  with  which  we  use  these  forces  will  largely  determine  the  success  of  any  system  of  heating 
and  ventilating  we  may  have  in  use.  It  is  better  to  assist  nature  than  to  work  against  her,  and  though 
this  is  so  manifest,  Ave  frequently  see  (so  called)  experts  trying  to  make  warm  air  go  in  a direction 
opposite  its  natural  course.  \\  e frequently  hear  it  said  that  the  open  window  is  the  best  form  of  ven- 
tilation, while  in  fact  it  is  the  very  worst,  because  the  air  obtained  through  an  open  window  does  not 
expel  the  foul  air  in  the  room,  but  simply  mixes  a certain  portion  of  cold  air  with  it  reducing  the 
temperature  to  some  extent,  and  making  it  more  bearable  but  very  little  purer,  as  a short  stud)  of  the 
question  will  soon  demonstrate. 

The  problems  here  touched  upon  we  have  been  studying  for  years,  and  have  gradually  conquered 
one  difficulty  after  another  so  that  Ave  can  now  design  a perfect  working  system  for  the  supply, 
warming  and  circulation  of  fresh  air  and  continuous  removal  of  foul  air  from  buildings,  and  furnish 
the  necessary  materials  to  construct  the  same.  Our  system  is  not  costly  in  construction  and  is  very 
economical  in  operation.

In  the  construction  of  this  Boiler  we  have  carefully  selected  the  form  best  calculated  to  utilize  to 
the  fullest  extent  the  natural  laws  provided  for  our  assistance.  The  provision  of  grate  surface  is  ample 
in  every  si/e  to  maintain  the  most  economical  rate  of  combustion  ; the  proportion  of  heating  surface  to 
grates  is  that  best  calculated  to  absorb  the  greatest  amount  of  heat  generated,  and  the  surface  is  so 
arranged  that  fully  ninety  per  cent  of  it  is  in  direct  contact  with  the  fire.  The  disposition  of  the  surface 
is  such  that  the  lire  passes  freely  at  the  upper  part,  where  it  is  needed  to  ensure  at  all  times  a quick  sup- 
ply of  dry  steam. 

I lie  arrangement  of  the  sections  is  such  that  at  all  times  a sufficiently  high  temperature  is  kept 
up  to  thoroughly  burn  the  gases,  and  to  utilize  to  the  fullest  extent  the  heating  power  of  the  fuel.  The

arrangement  of  the  water  and  steam  passages  in  the  sections  ensures  at  all  times  a perfect  circulation 
and  a quick  separation  of  the  steam  from  the  water,  which  is  a positive  prevention  from  foaming  or 
priming  of  the  water  in  the  boiler. 

I his  boiler  is  portable  in  form,  and  is  shipped  in  sections,  so  that  it  may  be  taken  in  at  any  ordi- 
nary door  or  window.  It  is  particularly  adapted  for  schools,  owing  to  its  simplicity  and  ease  of  manage- 
ment ; also,  from  the  fact  that  one,  two,  three  or  more  of  them  may  be  joined  together  to  provide  for 
large  buildings,  this  method  being  preferable  to  having  one  large  boiler.

“ Sun kav  ” Water  Heater. 


It  will  be  seen  from  the  above  illustrations  of  the  “Sun ray’’  Water  Heater  that  we  take  the  return 
water  in  at  the  bottom  of  the  ash  pit  where  it  first  absorbs  the  heat  radiated  from  the  grate  ; from  there 
it  passes  up  through  the  fire  pot,  across  the  two  sections  forming  the  arch  over  the  fire  pot,  and  then 
thr  ough  the  upper  sections  to  the  combustion  chamber  at  the  top,  (see  Plate  3-A),  encountering  a less 
amount  of  friction  than  is  met  with  in  any  other  heater  having  a positive  circulation. 

I lie  water  passages  in  the  sections  and  in  the  combustion  chamber  are  so  arranged  that  they 
expose  a very  large  amount  of  surface  to  the  heat  generated  from  the  process  of  combustion.  The  heat 
from  the  burning  fuel  passes  between  the  water  tubes  to  the  top  of  the  heater,  where  the  combustion 
chamber  utilizes  the  unconsumed  gases  in  the  further  generation  of  heat,  thus  making  the  top  of  the 
heater  and  the  intermediate  passages  as  hot  as  or  hotter  than  the  fire  pot. 

As  the  gases  become  cooled  by  contact  with  the  water  in  the  top  of  the  heater,  they  pass  down 
i lie  return  flues  at  the  back  of  the  heater  and  then  up  the  chimney.  The  return  fines  are  surrounded 
by  water  which  absorbs  all  the  heat  that  remains  in  the  gases  after  leaving  the  combustion  chamber.

It  is  well  known  that  heat  will  rise,  and  that  the  hottest  part  of  a furnace  or  oven  will  be  at 
the  top,  unless  artificial  obstructions  are  introduced  to  dellect  the  heat. 

This  cannot  be  done  in  a hot  water  heater  without  condensing  the  products  of  combustion  into 
carbonic  oxide  and  wasting  the  fuel.  Our  construction  allows  the  heat  to  rise  freely  to  the  top  of  the 
heater,  and  maintains  a higher  temperature  at  the  top  than  at  the  fire  pot,  thus  allowing  all  the  gases  to 
be  consumed  while  the  return  llues  prevent  the  escape  of  the  smoke  or  waste  gases  till  all  the  heat  has 
been  abstracted  from  them,  when  they  are  allowed  to  pass  to  the  chimney.

Arrangement  of  Fire  and  Combustion  Chambers. 


I'he  arrangement  of  our  return  flues  is  illustrated  by  plate  3-A.  The  flues  at  either  side  take  the 
waste  gases  down  and  the  central  one  allows  them  to  escape  to  the  smoke  pipe. 

Plate  4-A  illustrates  the  shape  and  arrangement  of  the  tubes  over  the  fire;  also  the  passages  from 
the  fire  pot  to  the  combustion  chamber  at  the  top  of  the  heater.  It  will  be  noticed  that  all  these  passa- 
ges are  direct  from  the  fire  pot  to  the  top,  allowing  the  gases  to  be  consumed  thoroughly  before  being 
cooled  by  contact  with  the  water  tubes  on  their  way  to  the  combustion  chamber. 

Idle  sides  of  the  fire-box  are  corrugated  in  such  a manner  that  perfect  combustion  of  the  fuel  takes 
place  to  the  edge  of  the  fire,  and  at  the  same  time  all  the  water  surrounding  the  fire-box  conies  in  con-

tact  with  the  burning  fuel.  No  fire-brick  lining  is  used  in  connection  with  this  heater,  hence  there  is 
none  to  burn  out. 

We  use  an  improved  form  of  rocking  grate  that  has  been  tested  in  furnaces  for  many  years,  and 
has  always  given  the  best  results.  It  is  very  easy  to  shake,  makes  little  or  no  dust,  does  not  waste  fuel, 
and  A so  simple  that  it  cannot  easily  get  out  of  order. 

The  labor  of  operating  our  heater  is  much  less  than  that  required  for  an  ordinary  furnace.  All 
the  flues  can  be  cleaned  out  with  little  trouble,  and  a few  minutes’  time  is  all  that  is  necessary  to  thor- 
oughly  clean  all  the  heating  surfaces  and  keep  the  heater  in  good  working  order. 


RADIATORS. 


We  herewith  illustrate  some  designs  of  Radiators  used  in  the  construction  of  our  Heating 
and  Ventilating  Apparatus. 


I'lie  above  illustration  shows  a cluster  of  a Pin  Radiator,  which  is  used  in  the  radiator  cham- 
bers placed  at  the  base  of  the  warm  air  lines.  It  will  be  seen  that  this  cluster  is  made  up  of  a 
series  of  sections,  between  each  of  which  there  is  space  for  the  air  to  circulate  through.  As  these 
are  filled  only  with  steam  or  water,  it  will  be  seen  how  impossible  it  is  to  in  any  way  burn  or  con- 
taminate the  air  passing  through  the  chamber.

Radiator  in  Position. 


I he  above  represents  a type  of  Semi-direct  Radiator,  which  we  use  in  old  buildings  when  it 
is  impossible  to  build  lines  to  carry  warm  air  to  the  rooms.  1 hese  Radiators  are  arranged  with 
lines  by  which  the  air  may  be  taken  from  the  outside  and  passed  through  the  Radiator  before  dis- 
charging it  into  the  room.  I'lie  quantit\  of  air  supplied  by  this  method  may  be  increased  or  dimin- 
ished to  ail)  extent  necessary.  When  school  rooms  are  heated  by  this  class  of  Radiator,  it  is  neces- 
sary to  have  some  means  by  which  the  foul  air  may  be  taken  from  the  lloor,  or  at  some  point  in 
the  wall  near  the  lloor  line.

OUR  TUBULAR  AIR  WARMER  AND  CIRCULATOR. 

For  those  schools  in  smaller  cities  where  heating  and  ventilating  by  hot  water  or  steam  is 

too  expensive,  we  design  an  apparatus  to  work  by  warm  air  furnaces.  In  using  this  method  we 

do  not  in  any  way  change  the  warm  air  or  foul  air  lines  as  will  be  shown  by  illustrations  in  sub- 
sequent pages.  The  only  change  is  made  in  the  placing  of  the  apparatus  in  the  cellar  of  the 
building.  Our  furnace  is  so  constructed  that  a very  large  amount  of  surface  is  presented  to  the 
air  passing  through  it.  It  is  easily  cleaned,  all  parts  being  large  and  accessible.  It  is  also  very 
durable,  being  of  heavy  cast  iron  and  steel.  It  is  adapted  for  hard  or  soft  coal,  but  can  be  easily 

changed  to  burn  wood.  In  operation  it  will  be  found  the  most  economical  of  heaters. 


OUR  SANITARY  WATER  CLOSET  AND  URINAL  RANGES. 


In  the  arranging  for  Closets  and  Urinals  in  schools,  it  is  imperative  that  the  very  best 
sanitary  appliances  known  to  the  present  age  should  be  used.  Our  Automatic  Syphon  and  \\  ash- 
out  Water  Closet  Ranges,  Latrines  and  Urinals,  have  been  designed  and  built  to  meet,  not 
only  the  conditions  required  by  the  most  advanced  sanitary  law's,  but  also  to  give  the  most 
practical  results.  These  Ranges,  as  may  be  observed  by  examining  the  illustrations  in  the  following 
pages,  are  all  placed  above  the  floor,  and  if  preferred  may  be  set  up  entirely  without  w'ood  wrork. 
They  are  so  exposed  that  all  parts,  both  inside  and  out,  are  accessible  to  admit  ot  easy  inspection, 
thus  preventing  accumulation  of  offensive  matter  remaining  unnoticed.  The  arrangement  for  water 
supply  to  these  fixtures  is  very  simple  ; the  automatic  part  can  be  adjusted  to  flush  the  apparatus 
with  water  at  any  interval  of  time,  while  the  “ direct  supply  ” can  be  operated  by  the  janitor  or 
person  in  charge  ; in  either  case,  the  wrater  need  not  be  wasted  when  the  closets  and  urinals  are 
not  in  use. 


LAVATORIES  AND  WASH  SINKS. 


Our  Lavatories  and  Wash  Sinks  illustrate  various  arrangements  that  will  largely  enhance  the 
sanitary  condition  of  schools  and  like  buildings  by  providing  convenient  means  for  the  pupils  to 
cleanse  themselves.  A description  of  each  will  be  found  under  the  illustration  on  pages.  36,  37, 
38,  39  and  40,  so  that  their  advantages  for  different  conditions  will  be  readily  seen.

PATERSON,  N.  J.,  PUBLIC  SCHOOL,  No.  I. 


1 his  building  was  erected  during  the  year  1894,  according  to  plans  prepared  by  Messrs.  C. 
bow  1 1 1 Carr,  (Union  Square,  New  York,)  and  Charles  J.  Post.  (Paterson,  N.  ).,)  Architects.  After 
examining  plans  from  several  Heating  and  Ventilating  Engineers,  the  plans  submitted  by  The  J.  L. 
M 011  Iron  Works  for  the  Heating-  and  Ventilating  were  selected  as  being  the  best,  and  were 
unanimously  adopted  by  all  parties  interested.  The  plates  on  the  following  pages  illustrate  the 
arrangement  of  the  different  rooms  on  each  floor.  Plates  on  page  19  show  a sectional  view  of  the 
main  vent  shaft  and  the  elevation  of  warm  air  and  foul  air  flues.  Plate  on  page  14  represents 
the  cellar  floor  by  which  the  arrangement  of  the  steam  boilers  and  the  system  of  piping  may  be 
full)'  understood.  In  the  boiler  room  are  located  three  Mott's  Sectional  “ Sunray  ” Steam  Boilers, 
arranged  in  one  battery  with  valve  connections,  so  that  one,  two  or  three  may  be  used,  as  needed. 
Prom  the  boilers  a system  of  steam  and  return  pipes  run  to  the  several  radiator  chambers,  (desig- 
nated on  plan  as  Rad.  Stacks),  and  from  these  chambers  run  the  warm  air  flues  to  heat  the  several 
class  rooms  in  the  various  stories,  there  being  a separate  chamber  for  each  class  room.  The 
arrangement  for  taking  fresh  air  from  the  outside  to  the  several  radiator  chambers,  is  also  shown 
on  this  floor.  The  next  plate,  page  15,  illustrates  the  ground  floor  on  which  are  arranged  two 
class  rooms,  the  principals’  and  teachers’  rooms,  also  the  play  courts  and  the  sanitary  water  closets. 
The  class  rooms  are  arranged  with  fresh  air  supply  and  foul  air  exhaust  flues,  as  indicated  by  darts 
in  each  room.  I he  teachers’,  principals’  room  and  halls  are  warmed  by  direct  radiators,  placed  as 
indicated  on  the  plan.  The  opening  of  the  doors  furnish  all  the  fresh  air  needed  for  halls. 

The  Water  Closet  arrangement  shown  on  this  floor  will  be  treated  separately. 

The  third  plate,  page  16,  illustrates  the  first  floor  of  the  building,  on  which  are  placed  six 
class  rooms  with  warm  air  supply  and  foul  air  exhaust  registers,  as  shown  by  the  darts  in  each 
room.  I he  cloak  rooms  are  placed  in  the  main  hall,  leaving  partitions  only  seven  feet  high.  From 
the  hall  a powerful  vent  is  taken  through  the  register  to  the  main  vent  shaft,  the  cloak  rooms  being 
thus  thoroughly  ventilated.  It  will  be  noticed  that  the  warm  air  in  each  room  is  projected  towards 
the  exposed  side,  this  being  the  best  way  to  procure  a uniform  temperature  in  all  parts  of  the  room. 
1 lie  fourth  plate,  page  1 7,  illustrates  the  second  floor,  which  is  almost  an  exact  duplicate  of  the 
first  floor,  the  arrangement  being  practically  the  same.  The  fifth  plate,  page  18,  illustrates  the 
third,  which  is  also  the  top  floor,  this  is  arranged  with  sliding  partitions,  by  which  the  recitation 
rooms  may  be  made  an  addition  to  the  large  assembly  room,  when  necessary.  The  position  of  the 
warm  air  inlet  to  each  room,  and  also  the  foul  air  outlet,  may  be  seen  by  the  darts  on  the  plan.  In 
rooms  16  and  17  the  partition  is  used  for  a vent,  and  is  connected  at  the  top  with  foul  air  flue 


I'lIE  |.  L.  MOTT  IRON  WORKS,  NEW  YORK, 


leading  into  main  vent  shaft.  The  sixth  plate,  page  19,  illustrates  a sectional  view  of  the  main 
vent  shaft,  and  the  elevation  of  warm  air  and  foul  air  lines.  It  will  be  seen  that  the  warm  air 
is  delivered  near  the  ceiling,  and  the  foul  air  is  taken  out  at  the  floor.  It  will  be  further  noticed 
by  looking  at  the  bottom  of  this  section  where  the  cold  air  enters  into  the  radiator  chamber  and 
flows  through  the  radiator  stack  up  into  the  warm  air  flue.  At  the  base  of  the  warm  air  flue 
is  placed  a mixing  damper,  connected  with  the  room  the  radiator  supplies  ; by  raising  or  lowering 
this  damper  with  the  chain,  the  air  in  the  room  may  be  changed  to  an)'  desired  temperature  without 
stopping  the  influx  of  fresh  pure  air  into  the  room.  The  damper  by  means  of  this  chain  is  entire!) 
under  the  control  of  the  teacher  in  the  room,  and  is  easily  regulated. 

SANITARY  WATER  CLOSETS  AND  URINALS. 

In  arranging  the  Water  Closets  in  this  building,  it  was  desired  that  the  rooms  for  them  should 
be  as  separate  from  the  building  as  possible.  With  that  end  in  view,  the  Closets  and  Urinals,  (as 

shown  on  the  basement  plan,)  were  placed  in  a one  story  annex  in  the  rear,  and  in  it  were 

arranged  Mott's  Automatic  Syphon  Closet  Ranges  for  the  girls’  room,  and  one  similar  Closet  Range, 
and  a Double  Flushing  Rim  Washout  Urinal  for  the  boys’  room.  These  Closets  and  Urinals  are 
supplied  with  water  by  self-acting  tanks,  which  may  be  adjusted  to  flush  at  any  interval,  say,  every 
ten  minutes,  or  once  per  hour,  as  may  be  necessary. 

These  rooms  are  heated  and  ventilated  in  such  a way  that  the  air  is  changed  in  them  every 
three  minutes,  and  the  fresh  air  is  taken  in  by  independent  air  ducts,  (separate  from  main  building), 
so  that  if  a back  draft  should  occur  the  air  from  these  closets  could  not  be  forced  into  the  class 
rooms.  When  in  operation,  the  draft  is  from  the  school  into  this  room,  so  that  it  a door  is  left 

open  the  air  will  flow  from  the  school  into  the  closets,  and  all  possibility  of  the  air  from  the  closets 

getting  into  the  class  rooms  is  avoided. 

WHY  THIS  SYSTEM  WAS  ADOPTED. 

It  was  the  desire  of  the  School  Board  to  confine  the  firing  to  one  room,  so  as  to  keep  the 
coal  and  ashes  in  a convenient  place  in  the  cellar.  It  was  also  desired  that  no  machinery  requiring 
skilled  labor  should  be  employed,  and  that  the  Heating  Apparatus  should  work  on  the  gravitv 
system  so  that  the  building  could  be  heated,  even  if  the  fans  from  any  cause  stopped  running.  It 
was  further  desired  that  some  efficient  means  of  ventilation  should  be  furnished  when  the  Heating 
Apparatus  was  not  being  used  in  warm  weather.  The  Apparatus  was  to  provide  ventilation  to  the 
extent  of  1500  to  1800  cubic  feet  of  air  per  hour  for  each  pupil  in  the  building  when  filled  to  its 
maximum  capacity,  and  the  temperature  was  to  be  maintained  at  70  degrees  in  zero  weather.  The 
system  described  meets  all  these  requirements.

NORTH  PLAINFIELD,  N.  J.,  PUBLIC  SCHOOL. 


The  following  description  of  the  Heating  and  Ventilating  Apparatus  is  taken  from  “ Heating 
and  Ventilation,”  March  15th,  1894: 

“The  accompanying  illustrations  of  a new  wing  recently  added  to  the  North  Plainfield,  New 
Jersey,  Public  School,  are  to  explain  the  method  of  heating  and  ventilating  adopted  on  the  recommen- 
dation of  the  architect.  The  heating  is  accomplished  by  indirect  hot  water,  and  the  ventilating  by 
the  aspirating  system.  The  requirements  to  be  met  were  to  warm  the  building  to  70  degrees  in 

zero  weather,  and  to  change  the  air  in  the  rooms  from  four  to  five  times  per  hour.  Owing  to  the 

new  wing  having  to  conform  with  the  old  structure,  conditions  were  met  with  that  would  not  have 

existed  in  an  entirely  new  building  ; besides  this  it  was  desired  that  all  the  rooms  should  be  arran- 

ged with  folding  partitions,  that  at  any  time  could  be  shoved  back  to  make  one  large  assembly  room. 
These  requirements  made  it  very  difficult  to  locate  the  exhaust  flues  where  they  would  do  the  best 
wrork,  and  at  the  same  time  conform  to  the  architectural  requirements  of  the  building.  Fig.  1 is  the 
cellar  plan  of  the  building,  showing  the  location  of  the  various  chambers  that  contain  the  stack  of 
radiators  through  which  the  air  is  circulated  before  entering  the  warm  air  flues  connecting  with  the 
various  rooms.  The  fresh  air  is  taken  in  by  two  main  air  ducts,  made  of  brick  and  placed  beneath 
the  cellar  floor.  Prom  each  of  these  main  ducts  branches  are  taken  to  the  various  chambers  as 

shown  by  dotted  lines.  The  foul  air  ducts  are  built  under  the  cellar  floor,  in  a similar  manner  to 

the  fresh  air  ducts." 

“ These  connect  the  bottoms  of  the  vertical  ducts  from  the  various  rooms  to  the  base  of 
the  main  shaft.  Heat  is  supplied  by  two  of  Mott’s  “ Sunray  ” Water  Heaters,  each  having  a capa- 
city of  3000  square  feet  of  direct  radiation.  It  will  be  noticed  that  the  flow  and  return  mains  in  a 

system  like  this  are  very  short,  owing  to  the  compact  grouping  of  the  stacks  that  this  method  of 

heating  admits  of.  Fig.  2 is  the  plan  of  the  first  floor,  showing  the  location  of  the  inlet  register  on  the 
wall  and  the  position  of  the  exhaust  register  in  the  floor  of  each  room  and  hall.  Fig.  3 is  a plan  of  the 
second  floor,  showing  lines  for  supplying  warm  air  and  the  position  of  exhaust  registers.  Fig.  4 is 
a section  through  the  radiator  stack  and  warm  air  flue,  showing  the  position  and  the  action  of  the 
mixing  damper.  Fig.  5 is  a section  on  line  A B,  [Fig.  2]  showing  the  method  of  taking  the  foul 
air  from  the  room  and  delivering  it  to  the  main  vent  stack.  Summer  ventilation  is  provided  for  by 
placing  a furnace  in  each  of  the  vent  stacks,  in  which  a fire  may  be  built  when  the  heating  appa- 
ratus is  not  in  use.  No  difficulty  was  experienced  during  the  recent  cold  weather  in  maintaining 
the  required  temperature  and  in  getting  the  needed  ventilation.  The  building  was  planned  by  Chas. 
II.  Smith,  Architect,  106  Broadway,  Ncav  York.  The  Heating  and  Ventilating  Apparatus  was  de- 
signed by  (.  J.  Blackmore,  superintendent  of  the  heating  department  of  the  (.  L.  Mott  Iron  Works, 
New  York,  and  the  work  of  placing  the  apparatus  was  done  by  C.  W.  Krausse,  of  Plainfield.”

ADVANTAGES  OF  THIS  SYSTEM. 


First: — A thorough  circulation  is  kept  up  by  a continuous  supply  of  fresh  warm  air,  and 
a system  of  lines  by  which  the  foul  air  is  taken  from  the  building. 

Second  : — A separate  heating  chamber  for  each  room,  which  leaves  no  chance  for  overheat- 
ing one  chamber  at  the  expense  of  another. 

I hird  .-—Each  room  being  independent  of  the  other  it  may  be  shut  off,  and  the  expense  of 
running  stopped  when  not  in  use. 

Fourth: — The  heat  being  supplied  by  hot  water,  it  is  impossible  to  overheat  the  air  or  in 
any  way  vitiate  it. 

Fifth  : — As  no  fire  or  furnace  is  in  any  way  connected  with  the  chamber,  there  is  no  possi- 
ble chance  for  gases  to  mingle  with  the  air. 

Sixth  : — 1 he  radiators  being  filled  with  hot  water,  prevent  all  possibility  of  sudden  changes 
in  the  temperature  even  if  the  fire  is  neglected.

MOTT’S  AUTOMATIC  SYPHON  WATER  CLOSE  I RANGE. 


Plate  1 2 1 1 -G. 


MOTT'S  PATENT  AUTOMATIC  SYPHON  WATER  CLOSET  RANGE,  LONGITUDINAL  SECTION. 

The  problem  of  constructing  an  Automatic  Water  Closet  Range  with  a large  deep  body  of  water,  and  at  the  same  time  simple  and 
reliable  in  action  has  been  solved  in  the  above.  The  area  and  depth  of  water  are  sufficient  to  receive,  submerge  and  deodorize  the  soil 
thereby  necessitating  less  frequent  flushing  than  is  required  in  the  Wash-out. 


DIMENSIONS. 

The  Range  is  regularly  made  with  Seats  of 
three  different  lengths,  viz.:  24  inches,  27  inches  and 
30  inches  from  centre  to  centre  of  openings,  or  from 
centre  to  centre  of  partitions  The  extreme  length  of 
Range  is  ten  24  inch  Seats,  nine  27  inch  Seats  or 
eight  30  inch  Seats  ; to  these  lengths  must  be  added, 


Plate  1212-G 


DIMENSIONS. 

say  1 foot  10  inches  for  Flush  Pipe  and  Trap. 
Height  from  Floor  to  top  of  Range  including  Wood 
Seat.  1 foot  6 inches  ; Height  from  Floor  to  top  of 
Iron  Partitions,  5 feet  10  inches;  Depth  of  Partitions, 
2 feet  2 inches  ; Width  of  Range  from  front  to  back, 
1 foot  7 inches. 


Cross  Section  showing  the  Auxiliary  Flush  Pipes,  which  thoroughly  wash  the  front  and  back  of  Range  every  time  the  Cistern  operates. 


Mott’s  Automatic  Syphon  Water  Closet  Range  is  extremely  simple  in  operation,  and  there  are  no  moving  or  mechanical  parts  liable 
to  get  out  of  order.  When  the  Cistern  automatically  discharges,  the  air  is  rarefied  in  Upper  Trap  ; this  starts  a strong  syphon  and  the 
contents  of  Range  are  quickly,  forcibly  and  thoroughly  drawn  out,  after  which  the  Range  is  filled  to  the  normal  level  with  clean  water  from 
the  Cistern,  and  is  again  ready  for  use.  The  outgo  is  assisted  by  the  water  entering  the  Range  which  is  thoroughly  flushed  ; this  is  an 
important  feature  taken  in  connection  with  the  fact  that  in  this  Range  no  water  is  wasted  in  starting  the  Syphon,  but  all  the  water  from  the 
Cistern  passes  through  the  Range  and  cleanses  the  interior  of  the  same.  The  Patent  Automatic  Flushing  Cistern  can  be  regulated  to 
discharge  at  any  desired  interval. 

The  Range  is  entirely  of  cast  iron,  and  is  furnished  Painted  or  Porcelain-lined.  The  top  upon  which  the  Wood  Seats  rest  is  Cast  Iron. 
Painted  or  Porcelain-lined  underneath  so  that  all  parts  of  the  inside  of  the  Range  which  come  in  contact  with  the  water  are  non-absorbent.

Cross  section  showing  the  Auxiliary  Flushing- 
Pipes  which  thoroughly  wash  the  front  and  back  of 
Range  every  time  the  Cistern  operates. 

These  Pipes  are  of  Perforated  Brass  and  are  much 
preferable  to  Galvanized  Iron  which  soon  stop  up 
with  rust.

Branch  for  connecting  the  outlets  of  2 Ranges  placed  end  to  end. 

Diameter  of  outlet  of  Branch,  6 inches. 

Price,  • • ....  $3  00 


The  Range  is  regularly  made  with  Seats  three  different  sizes,  viz  ; 2 feet,  2 feet  3 inches  and  2 feet  6 inches  from  centre  to  centre  of 
openings,  or  from  centre  to  centre  of  Partitions.  The  extreme  length  of  Range,  is  ten  2 foot  Seats,  nine  2 foot  3 inch  Seats,  or  eight  2 foot 
6 inch  Seats  ; to  these  lengths  must  be  added,  say  9 inches  at  end  for  Flush  Pipe  from  Cistern.  When  more  than  10  Seats  are  desired  in 
one  line,  two  Ranges,  one  Right  and  one  Left  can  be  used  end  to  end  as  shown  by  Plate  982-G. 

Height  from  floor  to  top  of  Range  including  Wood  Seat  is  17  inches  ; (when  Range  is  to  be  used  in  schools  by  the  smaller  children,  we 
furnish  a lower  leg  making  the  height  from  floor,  14  inches.)  Height  from  floor  to  top  of  Iron  Partition,  5 feet  9 inches  ; width  of  Partition, 
single  Range,  2 feet  2 inches  ; width  of  Partitions,  double  Range.  4 feet  4 inches. 

The  2 and  3 Seat  Ranges  have  an  S gallon  Cistern  ; the  4 and  5 Seat  a 10  gallon  ; the  6 and  7 Seat  an  18  gallon,  and  the  larger  sizes  a 
27  gallon  Cistern. 

The  Patent  Automatic  Flushing  Cistern,  which  can  be  regulated  to  go  off  at  any  stated  interval,  is  of  great  power 
and  will  thoroughly  cleanse  the  Range  every  time.  The  Brass  Flushing  Pipes  placed  immediately  under  the  seat,  as  shown  by 
Section  Plate  387  G,  wash  the  front  and  back  of  Range  so  that  no  urine  or  other  matter  can  adhere.  If  preferred,  we  can  furnish  the 
Range  with  a Ready-supply  Cistern,  i e.  Cistern  with  Ball-cock  Supply,  to  be  operated  by  janitor  or  person  in  charge  at  such  intervals  as 
may  be  deemed  necessary.  Of  course,  this  Cistern  being  supplied  with  a Ball-cock  will  always  be  full  of  water,  and  read}"-  to  be  discharged 
at  any  time.

The  Outlet  of  Trap-Standard  is  3 inches.  back  of  Urinal  each  time  Cistern  operates. 

Nothing  so  complete,  and  at  the  same  time  so  thoroughly  sauitary  has  ever  been  made  in  the  form  of  a l rinal  for  use  in  public 
places,  such  as  Railroad  Depots,  Schools,  Barracks,  Work  Shops,  and  other  large  buildings,  where  strength,  durability  and  cleanliness  are 
desired.  In  operation  it  is  very  simple  The  Flushing  Cistern  can  be  set  to  flush  at  any  interval  desired,  when  every  part  of  the  LTrinal  is 
thoroughly  flushed  and  washed  out.  It  is  also  complete  in  itself,  requiring  only  connections  to  be  made  to  the  supply  and  waste  pipes. 
One  of  the  most  important  features,  however,  is  that  there  is  always  a body  of  water  to  receive  and  dilute  the  urine,  thus  avoiding  the 
offensive  odor  arising  from  urine  falling  on  a dry  surface. 


DIMENSIONS  OF  PLATE  TI92  G. 

Width  of  Urinal,  9 y2  inches  ; depth,  b'/2  inches  ; height  to  top  of  Urinal  at  front,  1 foot  g'/2  inches  ; height  to  top  of  back,  3 feet  10  inches  ; 
height  to  top  of  Partitions,  5 feet  5 '/2  inches  ; width  of  Partitions,  1 foot  6 inches  ; diameter  of  Trap-Standard,  3 inches. 

The  Pipe  we  send  to  connect  Flushing  Cistern  to  Urinal  raises  bottom  of  same  about  24  inches  above  Partitions  : where  ceilings  will  not 
admit  of  that  height  it  can  be  cut  off,  although  it  is  preferable  to  have  Cistern  as  high  as  possible,  particularly  with  the  larger  sizes 
of  Urinals.

Plate  1193-G,  is  adapted  for  use  where  the  conditions  are  such  that  the  Urinal  is  preferably  placed  in  the  centre  of  an  apartment 
instead  of  against  the  wall.  It  is  unquestionably'  the  most  desirable  and  compact  appliance  of  the  kind  that  has  yet  been  devised  No 
Woodwork  or  Marble  is  required,  the  Urinal  being  complete  in  itself,  and  involving  very  little  expense  to  put  it  up  The  water  contained 
in  each  Urinal  (see  Sectional  view  and  description  page  29),  dilutes  the  LTrinal  and  prevents  the  offensive  smell  so  common  to  most  Urinals.

Porcelain-lined  Iron  Fittings. 

Plate  5S0-G  shows  the  Stevens’  lTrinal  set  up  with 
Porcelain  lined  Iron  Fittings.  The  advantages  of  this  sys- 
tem of  drainage  and  ventilation  must  be  at  once  apparent 
to  all  those  who  have  given  any  attention  whatever  to  the 
subject  of  Urinals.  It  is  a well  known  fact  that  nothing  in 
the  whole  line  of  plumbing  is  so  difficult  to  handle  as  this 
matter  of  Urinals,  and  no  amount  of  water,  no  matter  how 
applied,  will  keep  a line  of  Urinals  in  any  public  building 
sweet  and  clean,  unless  they  are  properly  ventilated,  and  no 
more  perfect  or  simpler  system  than  Mr  Stevens’  can  well 
be  imagined  ; i.e. , where  a Hot  Flue  can  be  had  in  which  to 
run  the  Vent,  otherwise  the  principal  feature  of  the  system 
is  lost ; this  is  very  readily  found  as  a general  thing  in  all 
large  buildings,  and  there  is  no  trouble  in  carrying  out  the 
system  when  the  plans  are  arranged  for  it.  As  shown,  the 
LTrinal  has  a 2 '/z  inch  open  outlet,  i.e.,  no  strainer,  thus 
allowing  all  matter  (which  is  usually  dropped  into  the 
Urinals  to  lie  there  until  taken  out  by  hand),  to  pass 
through  and  be  carried  off  same  as  matter  from  a Water 
Closet.

The  “ Undine  ” is  a strictly  first-class  Front-Outlet 
Wash-out  Water  Closet.  It  is  efficient  in  operation 
and  without  any  moving  or  mechanical  parts  liable 
to  get  out  of  order,  and  it  is  also  of  the  best  English 
ware  warranted  not  to  craze  or  discolor.  The 
Flushing-Rim  is  designed  to  give  the  greatest  wash- 
out force  with  the  least  amount  of  water,  and  to  in- 
sure all  parts  of  the  Bowl  being  flushed. 


Whenever  the  supply  comes  from  the  floor,  no  ar- 
rangement has  yet  been  devised  equal  to  the  Com- 
bination Flush  and  Supply  shown  above.  The 
Supply  Pipe  is  immediately  behind  the  Flush  Pipe, 
and  the  latter  being  larger,  the  Supply  is  not  seen 
when  standing  in  front  of  the  Closet ; thus  the  sym- 
metrical appearance  of  the  Closet  is  maintained 
which  is  not  the  case  when  the  supply  is  at  the  side 
of  the  Cistern.  Both  practically  and  in  appearance 
the  Combination  Flush  and  Supply  will  instantly 
commend  itself. 


The  “Undine”  with  our  new  “Perfecto”  Seat, 
represents  in  the  fullest  sense  of  the  term,  an  “ All- 
Open ’’Water  Closet.  By  a simple  and  effective 
method  the  Seat  is  secured  directly  to  the  Bowl.  A 
most  important  feature  is  the  complete  accessibility 
of  the  space  back  of  the  Closet  so  that  it  can  readily 
be  kept  clean. 

With  the  No.  4 ]/z  Cistern,  a slight  pull  starts  the 
Syphon  and  insures  a thorough  flush  of  the  Closet; 
Dimensions,  18  X 9 X 10  in.  deep;  Capacity,  3 gallons. 

The  No.  25  Cistern  has  a slow  closing  Valve  ;

THE  “PRIMO"  DIRECT-ACTION 
SYPHON-JET  WATER 
CLOSET. 

Patented  Dec.  7,  1880;  Aug.  9,  1892;  Dec.  12,  1803; 
other  patents  pending. 

The  “ Primo  ” is  a first-class  Syphon-Jet  Water 
Closet,  simple  in  construction  and  operation.  The 
Earthenware  is  of  the  best  English  manufacture 
warranted  not  to  craze  or  discolor.  The  bowl 
contains  a large  bod}^  c f water,  and  there  are 
no  mechanical  parts  liable  to  get  out  of  order. 
When  the  pull  is  drawn  down  the  Syphon  is 
started  and  contents  of  Bowl  are  quickly  and 
almost  noiselessl}T  ejected.  The  Jet  in  addition  to 
starting  the  Syphon,  acts  upon  the  water  in  the 
Bowl  and  facilitates  the  outgo,  so  that  but  a 
limited  quantity  of  water  (2  to  3 gallons),  is  re- 
quired for  each  flush. 

Where  the  Supply  comes  from  the  floor  no 
arrangement  has  yet  been  devised  equal  to  the 
Combination  Flush  and  Supply,  as  shown  above. 
The  Supply  Pipe  is  immediately  behind  the  Flush 
Pipe  and  the  latter  being  the  larger,  the  Supply 
Pipe  is  not  seen  from  the  front  of  the  Closet. 
Thus,  the  symmetrical  appearance  of  the  Closet 
is  maintained,  which  is  not  the  case  when  the 
Supply  is  at  the  side  of  the  Cistern.  Both  prac- 
tically, and  in  appearance,  the  Combination  Flush 
and  Supply  will  instantly  commend  itself.

The  illustrations  represent  a Sink  in  which  a greater  or  less  number  of  men  can  wash  together.  The  extreme  length  that  we  can  furnish  the 
Wash  Sink  is  55  feet  consisting  of  11  Sections  each  5 feet  long,  the  Section  with  Waste  being  in  the  centre  with  5 Sections  to  the  right  and  left  all 
draining  toward  the  centre.  The  width  of  Sink  is  1 foot  6 inches;  the  depth  of  centre  Section  is  8 inches;  the  depth  of  the  extreme  end  Sections  is 
5 inches;  the  Back  is  15  inches  high.  Plate  1126-G  shows  only  two  Sections  on  each  side  of  Waste  Section  Any  number  of  Sections  from  x to  11 
will  be  furnished  as  may  be  ordered.  Where  the  Sink  turns  a corner,  it  is  made  as  shown  b}r  Plate  112S-G,  in  which  case  the  Waste  must  be  in 
the  corner,  as  shown. 

Various  methods  of  supply  can  be  used  to  suit  local  requirements.  The  one  shown  consists  of  two  Compression  Faucets  for  cold  water  for 
each  Section,  and  one  hot  water  Faucet,  which  may  be  placed  in  centre  as  shown,  or  any  other  convenient  part  of  the  Sink;  the  supply  is  preferably 
through  Wrought  Iron  Pipe  For  the  first  wash  (to  remove  dirt  and  soot)  hot  water  is  desirable;  this  can  be  obtained  by  filling  the  Sink  with  water 
of  a desired  temperature  through  the  hot  and  cold  Faucets;  after  this  first  wash  all  the  men  can  use  the  cold  water  Faucets  individually  for  cleans- 
ing and  rinsing,  using  the  water  as  it  falls  from  the  open  Faucets.
